The last time that the four trajectory thrusters on the Voyager 1 probe were fired, Jimmy Carter was still President of the United States. But with the main attitude control thrusters deteriorating from trying to keep the probe oriented correctly, the team thought they could keep the mission going using the trajectory thrusters. So they fired them up.

On Tuesday, Nov. 28, 2017, Voyager engineers fired up the four TCM thrusters for the first time in 37 years and tested their ability to orient the spacecraft using 10-millisecond pulses. The team waited eagerly as the test results traveled through space, taking 19 hours and 35 minutes to reach an antenna in Goldstone, California, that is part of NASA’s Deep Space Network.

Lo and behold, on Wednesday, Nov. 29, they learned the TCM thrusters worked perfectly — and just as well as the attitude control thrusters.

Voyager 1 was launched in 1977, is currently more than 13 billion miles from Earth, and is still functional and doing science. Incredible.

In the winter of 1976, Carl was visiting with me and my fiancee at the time, Ann Druyan, and asked whether we’d help him create a plaque or something of the sort for Voyager. We immediately agreed. Soon, he and one of his colleagues at Cornell, Frank Drake, had decided on a record. By the time nasa approved the idea, we had less than six months to put it together, so we had to move fast. Ann began gathering material for a sonic description of Earth’s history. Linda Salzman Sagan, Carl’s wife at the time, went to work recording samples of human voices speaking in many different languages. The space artist Jon Lomberg rounded up photographs, a method having been found to encode them into the record’s grooves. I produced the record, which meant overseeing the technical side of things. We all worked on selecting the music.

Carl Sagan was project director, Ann Druyan the creative director, and Ferris produced the Record. And the sound engineer for the Golden Record? I was surprised to learn: none other than Jimmy Iovine, who was recommended to Ferris by John Lennon.

I sought to recruit John Lennon, of the Beatles, for the project, but tax considerations obliged him to leave the country. Lennon did help us, though, in two ways. First, he recommended that we use his engineer, Jimmy Iovine, who brought energy and expertise to the studio. (Jimmy later became famous as a rock and hip-hop producer and record-company executive.)

Lennon, Springsteen, Tom Petty, Patti Smith, Stevie Nicks, Interscope, Dre, Snoop, Death Row Records, Eminem, Lady Gaga, Beats By Dre, Apple, *and* The Golden Record? Iovine is like the record industry’s Forrest Gump or something. How was this not in The Defiant Ones?

The Voyager Golden Record contains the story of Earth expressed in sounds, images, and science: Earth’s greatest music from myriad cultures and eras, from Bach and Beethoven to Blind Willie Johnson and Chuck Berry, Senegalese percussion to Solomon Island panpipes. Dozens of natural sounds of our planet — birds, a train, a baby’s cry — are collaged into a lovely sound poem. There are spoken greetings in 55 human languages, and one whale language, and more than one hundred images encoded in analog that depict who, and what, we are.

This is so cool. When I was doing the packages with Quarterly, one of the ideas I had on my list was to replicate the Golden Record. The production values would have been a lot more limited than this effort and the rights issue is ultimately why I never pursued it:

The overwhelming majority of the funds raised from this historic reissue will go directly to the high production costs, licensing, and royalties incurred in creating this lavish box set.

When they were launched in 1977, the two Voyager spacecraft each carried with them a 12-inch gold-plated copper record containing images and sounds of Earth for the viewing pleasure of whichever aliens happened across them. NASA has put the sounds of the Golden Record up on Soundcloud. Here are the greetings in 55 different languages (from English1 to Hittite to Polish to Thai):

What’s missing from the two playlists is UN Secretary General Kurt Waldheim’s greeting:

…as well as several other UN greetings overlaid with whale sounds:

Due to copyright issues, also missing are the 90 minutes of music included on the record. Among the songs are Johnny B. Goode by Chuck Berry, The Rite of Spring by Stravinsky, and Dark Was the Night, Cold Was the Ground by Blind Willie Johnson. Here Comes the Sun by The Beatles was originally supposed to be included, but their record company wouldn’t allow it, which is pretty much the most small-minded thing I have ever heard.

The English greeting was spoken by Nick Sagan when he was six years old. Nick is the son of Carl Sagan, who chaired the committee that selected the contents of the record.↩

When they were launched in 1977, the two Voyager spacecraft each carried with them a 12-inch gold-plated copper record containing multimedia pertaining to life on Earth, the idea being that if an extraterrestrial ran across one of these records millions of years from now, they could play it an learn something about our planet. This site has a listing of some of the music, images, and sounds contained on the records. Here are two of the images included…the first is a rudimentary mathematics primer and the second is a family portrait:

I wonder when we’ll see these records again. I mean, it seems more plausible that Elon Musk’s grandson will mount an expedition to retrieve a Voyager probe in 2077 than some alien running across the thing.

“The wind, rain, and surf sounds are pretty cool, but I usually sort of zone out when it gets to the crickets chirping, and then I just end up turning it off,” said Ellinger, adding that he will sometimes put the record on as background noise when he’s cleaning his electro-biological habitat.
